Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx cu&,J#r%  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm +Llo81j&  
Type: Double Bounces FB:<zmwR  
The '****' denotes a possible internal focus :B|Dr v  
RMS is the RMS spot radius on axis at the primary wavelength. [u M-0t  
RMS values of 0.00 indicate that an accurate RMS ZDx@^P y  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is Xl_Uz8Hp  
non-rotationally symmetric or uses non-standard surfaces.
